The GatewayClient API offers methods to construct and shutdown the GatewayClient, grab the connection information of the underlying network interface, interact with Devices, as well as add/remove event listenershandlers, and perform firmware upgrades of the underlying network interface (i.e. module). It also offers some network management methods.
